How many ways can Microsoft tick off its partners in the wake of the Surface tablet announcement? Well, here's another.

At issue is Microsoft's access to PC makers' designs, said Patrick Moorhead, president of Moor Insights & Strategy and formerly an executive at Advanced Micro Devices.

"Microsoft looked at what the [PC makers] were doing, seeing if it could meet their Windows 8 needs and then took action based on that," he said in a phone interview, citing conversations with -- and the sentiment of -- senior level executives at top-tier PC makers.

Moorhead continued. "If Microsoft had seen compelling enough plans from [PC makers], they wouldn't have needed to do this," referring to the Surface launch.

The problem, of course, is that Microsoft received that confidential information about partners' products before announcing that it would, in essence, compete against those very same companies.
